Experts maybe freezing bananas if Celsius drops (3,5)
I believe the answer is:
old hands
'experts' is the definition.
(old hand is a kind of expert)
'freezing bananas if celsius drops' is the wordplay.
I cannot quite understand how this works, but
'bananas' could be 'hand' (I've seen this before) and 'hand' is found in the answer.
The remaining letters 'olds' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'maybe' acts as a link.
Can you help me to learn more?
(Other definitions for old hands that I've seen before include "Experienced folk" , "Experienced people who have given long service" , "Experts" , "Experienced persons" , "Veterans" .)
